What is BaZi (Four Pillars)?

BaZi, or Four Pillars of Destiny, is a Chinese metaphysical system that analyzes a person's birth year, month, day, and hour to derive their destiny pillars. The app calculates all eight characters (天干地支), five-element interactions, ten gods, major cycles, and annual luck cycles with full accuracy.

Does the app run offline?

Yes. All core features — BaZi chart construction, Zi Wei Dou Shu charting, auspicious date selection, marriage compatibility, name analysis and ganzhi dictionary — compute on your device. No network is required after install.

What is Zi Wei Dou Shu?

Zi Wei Dou Shu is a traditional Chinese astrology system using 14 major stars arranged across 12 palaces derived from birth data. The app builds a complete chart with all major and minor stars, the Four Transformations (四化), and palace-by-palace breakdown.

Can I search auspicious dates for multiple events at once?

Yes. The auspicious date module supports multi-event combined search across 30+ matters (marriage, moving, opening, signing, traveling, etc.). Results show the intersection score for all selected events with daily and hourly granularity.

Is my birth data private?

Yes. All birth information and chart records remain on your device. The app uses no analytics SDK and no behavioral tracking. Network is used only for store billing.

Is this app for fortune-telling?

No. The app is positioned as a cultural research tool for traditional Chinese metaphysics. All content is derived from classical texts and is for cultural study and reference only — not a prediction of future events, medical advice, legal opinion or investment guidance.
